W. ; 1122, Jackson Avenue, River Forest, Illinois, U.S.A.) April 16, 1930, No. 12106. Convention date, Aug. 15, 1929. [Classes 100 (i) and 100 (ii).] In sheet folding and collecting mechanism for a printing-press, in which a folding-cylinder 12 and a cutting and collecting cylinder 14 rotate in operative relationships, means engaging the shafts 13, 15 are provided for bracing the cylinders against bowing outwardly away from each other between their ends. For this purpose, in addition to bearings for the shafts 13, 15 of the cylinders being provided in the main frames 10, 11 as usual, a third set of bearings is provided in a heavy yokeshaped member 34 rigidly fixed to the outside of the frame 11. The gears 32, 33 coupling the shafts 13, 15 are mounted thereon between the frame 11 and the member 34 which thus helps to prevent any springing apart of the gears. In order to lessen the wear on the gear wheels due to the heavy load thereon while the cutters are operating and to promote smooth running, flywheels 35, 36 are fixed to the shaft 15 at each end thereof.

Title: Improvements in and relating to semi-conductor rectifier units
Inventor: MCCUTCHAN JOHN CHARLES
IPC: H01L23/473
Filed: 1956-04-20
Abstract: 832,979. Semi-conductor devices. ENGLISH ELECTRIC CO. Ltd. April 18, 1957 [April 20, 1956], No. 12121/56. Class 37. A method of making a semi-conductor rectifier unit comprising two body members and a seal defining an enclosure within which a semiconductor rectifier element is situated is characterized in that during the final stages of the assembly together of the members and seal at least a part of the unit is heated whereby dimensional changes on subsequent cooling places the rectifier element in compression. In the embodiment shown a first sub-assembly is formed by brazing one of the metal ends 19 of the metal and glass seal 13 to a terminal member 10. The terminal member consists of a brass sleeve 10a housing an internallythreaded flanged copper cylinder provided with radial cooling passages 14. A second subassembly is formed by soft soldering a fused junction-type of diode 12 base plate downwards to the face of a second terminal member 11. This member is similar to member 10 except that the internally-threaded cylinder 10b is replaced by an extended cylinder 11b threaded at 16. After the copper face of member 10 has been tinned with a low-melting point solder and heated to just above the melting point of indium the sub-assemblies are brought together in a jig. As soon as the member 10 has become bonded to the indium electrode 22 of the junction diode it is cooled by circulating water through it. The metal part 20 of the seal is then heated inductively to braze or solder it to member 11 at D while the remainder of the assembly is maintained at a lower temperature by circulation of water through members 10 and 11. During the cooling operation, following the completion of the joint D, the contraction of the metal part 20 places the junction diode in compression. The fused junction diode is made by assembling an indium disc, an N-type germanium disc and a base plate tinned with an antimonious soft solder in superposed relationship and heating to fuse them together. In a modification the base plate may be omitted and the germanium disc soldered directly to member 11.

Title: Improvements in and relating to dies for use in the manufacture of tiles for walls, fire places and the like
IPC: B28B7/20
Filed: 1933-04-26
Abstract: 400,107. Moulding tiles with pressing plungers and dies. MILLWARD, E. F., Ben-mil, Whitmore Road, Newcastle-under- Lyme, and WOODS TILERIES (HANLEY), Ltd., Derby Street, Hanley, both in Staffordshire. April 26, 1933, No. 12141. [Class 87 (ii).] Comprises modifications in detail in the type of apparatus for forming undercut recesses in the backs of tiles in which a disc provided with radial serrations is rotated by a pin-and-slot connection with a spring-pressed plunger operated by the movement of the lower die member. In the present construction the formation of undercut recesses in the lower die box is avoided and the plunger is fixed by contact with the die box wall during the moulding operation and released to rotate the disc when it passes above the top of the die box. In the illustrated form the lower die is fitted with a rotary table 2 having a serrated upper surface. The table is mounted on a central pin retained in a bore in the die by the engagement of a screw 12 with a circumferential slot in the pin. A downwardly-projecting pin 5 near the periphery of the table engages a sliding member 6 controlled by the spring 8. When the dies are in the lowest or charging position, the member 6 is forced inwards to compress the spring by engagement with the wall of the die box 9. On elevating the moulded article to discharge it, the spring restores the member 6 and rotates the table sufficiently to free the serrations to enable the tile to be lifted up. The die box can be used either way up in the present apparatus. The serrations are preferably arranged in tangential formation and two or more tables may be fitted to each die if necessary.

Abstract: 1482464 Electric resistance heating BOC INTERNATIONAL Ltd 7 March 1975 [20 March 1974] 12401/74 Heading H5H A through flow fluid heater comprises a fluid permeable mass of electrically conductive material (e.g. carbon fibres or carbon coated fibres) 12 within a tube of electrically non-conducting material (e.g. glass) 2 between fluid permeable electrically conducting plugs 8 (e.g. of sintered metal) which connect the electrical supply with the heating conductor at points as widely spaced as possible on the fluid flow path. A further non-conducting tube 14 may pass coaxially through the first. Electrical connections to plugs 8 are via conductive extensions to one or both tubes, 4, 4, Fig. 1 and 4, 22, Fig. 3. To provide terminals at the same end of the heater, a conductive sleeve 20 may line the inner tube and is connected to the extension of the inner tube. Cold fluid passes through the central tube and is mixed with the heated fluid in a chamber 18. By keeping constant flow late through the heated tube, current supply and voltage, temperature of the mixed fluid leaving chamber 18 can be controlled by altering the rate at which cold fluid is supplied to the inner tube 16. A number of either sort of heater can be used together to give a greater volume of heated fluid. They are connected electrically in series and fluidically in parallel (Fig. 4, not shown).

Abstract: 1,202,717. Stress limiting devices. COAL INDUSTRY (PATENTS) Ltd. 15 March, 1968 [17 March, 1967], No. 12573/67. Heading B8B. A power cable 24 extending between a fixed power source and a movable coal mining machine, is hauled along the coal face by the resilient equipment shown, the outer casing 10 of which is mounted on the machine and any excessive tension in the cable 24 is relieved by the resilient equipment up to a point where the machine is automatically switched off. A cable grip 22 is connected to a rod 18 slidable within a tube 14 and including a piston 30 which compresses a spring 42 against an abutment 40 in the tube 14, when the cable 24 is tensioned. With increase in cable tension above a pre-determined limit, the mining machine is switched off via chains 44, 50 and adjuster 46 coupled to the piston 30. Any further increase in cable tension due to overrun of the machine causes a cam 32 on the rod 18 to actuate pawls 34 which permit the tube 14 to slide out of the tubular casing 10 to further release tension in the cable. A further spring may be connected to the chain 50 to facilitate further machine overrun without chain breakage. In a modification the spring 42 is replaced by either a rubber spring or a stack of spring washers.
